    ATK Optical Sensor Help

    I need help setting up an alert and decided to reach out to the pros; after spending the last 4 hours researching....

    I flooded my office because I left my RODI unit on to top off tank. Had an ATK in the box for a couple months and just was lazy to hook it up In either case, now I hooked it up and am paranoid to get it right. I have 4 optical sensors, 2 hooked up to the ATK and 2 on my RODI reservoir tank, my low position sensor on my reservoir tank goes from open to closed quickly at random times. I fixed this by deferring fill and alert for 5 min but it made me not trust the optical sensors... The back up for overfill is the float valve on the ATK but there is nothing "That I know of" for the low level sensor of the ATK if it gets stuck in the closed position. I have 2 CORE 20s and I assume they will alert me/turn off if they run dry.

    So to make a long story short; I would like to set up an alert for my low level ATK sensor. If it gets stuck in the closed position for say, 360 minutes, I would like to get an alert. That to me, would mean the sensor went bad and my tank is running low.

    This is the principle to alert for any stuck position.

    LowStuck
    Set OFF
    If SwitchName CLOSED Then ON
    Defer 360:00 Then ON

    Email
    If Output LowStuck = ON Then ON
